Abstract

1463352 Cleaning pressure filters ENGLISH CLAYS LOVERING POCHIN & CO Ltd 1 April 1975 [10 April 1974] 16037/74 Heading BID A method of removing residual solid particles from the pores of a filter element (4) of a tube pressure filter 1 comprises (a) washing the filter element on the inner tubular body with an aqueous cleaning solution (e.g. an acid or ammonium compound solution) in which the solid particles are at least partly soluble (b) washing the filter element on tubular body with water or an aqueous soap or detergent solution. An hydraulic fluid in compartment 8 may be supplied or withdrawn through valves 13 and 18 to cause wash solutions to pass to and fro through element 4 under influence of inflatable impermeable sleeve 3. Filter cake is removed by lowering inner tubular body 3 from the filter and applying an air blast through valve 19.
